I just thought of something. The night kill only make sense if whiteflame is scum. If he killed castin he could never fake claim that he was a doctor and healed castin. Castin was the obvoius night kill so whiteflame avoided killing him to get fake town cred.
If whiteflame is scum then I think scum really messed up the last night phase. Whiteflame should not have made any night kill, claim to be town who saved castin from being killed, and then everyone would be lynching mikal nowt hat it is confirmed he visited castin
